\(** .. @PROGRAM@ - demangle C++ symbols

@PROGRAM@ "[\|" -_ | --strip-underscores "\|]" "[\|" "-s {gnu,lucid,arm,hp,edg} " | " --format={gnu,lucid,arm,hp,edg}" "\|]" "[\|" --help "\|]" "[\|" --version "\|]" "[\|" symbol "...\|]"

The C++ language provides function overloading, which means that you can write many functions with the same name (providing each takes parameters of different types). All C++ function names are encoded into a low-level assembly label (this process is known as mangling\c ). The @PROGRAM@ program does the inverse mapping: it decodes (demangles) low-level names into user-level names so that the linker can keep these overloaded functions from clashing.

Every alphanumeric word (consisting of letters, digits, underscores, dollars, or periods) seen in the input is a potential label. If the label decodes into a C++ name, the C++ name replaces the low-level name in the output.

You can use @PROGRAM@ to decipher individual symbols by specifying these symbols on the command line.

If no symbol arguments are given, @PROGRAM@ reads symbol names from the standard input and writes the demangled names to the standard output. All results are printed on the standard output.

-_

--strip-underscores On some systems, both the C and C++ compilers put an underscore in front of every name. For example, the C name foo gets the low-level name _foo . This option removes the leading underscore.

"-s {gnu,lucid,arm,hp,edg}"

--format={gnu,lucid,arm,hp,edg} GNU nm can decode five different methods of mangling, used by different C++ compilers. This option selects which method it uses: the one used by the GNU compiler, the one used by the Lucid compiler, the one specified by the C++ Annotated Reference Manual, the one used by the HP compiler and the one used by the EDG compiler. The default is the GNU style.

--help Print a summary of the options to @PROGRAM@ and exit.

--version Print the version number of @PROGRAM@ and exit.
